19 Possible Causes for Amnesia, Cerebrospinal Fluid Abnormality, Frontal Intermittent Rhythmic Delta Activity

  • Stroke

    […] of the limbic system, and stroke is the only etiology of amnesia that can delineate the entire pathway of memory and critical convergence points. (3) Stroke also impairs[] In most cases, it occurs in a rhythmic and intermittent manner, and the most commonly and important types are frontal intermittent rhythmic delta activity (FIRDA) ( Fig 2[] Papanicolaou, AC, Levin, HS, Eisenberg, HM, Moore, BD, Goethe, KE, High, WM Evoked potential correlates of posttraumatic amnesia after closed head injury.[]

  • Subarachnoid Hemorrhage

    […] for SAH; CT negative for SAH and inconclusive cerebrospinal fluid examination.[] Transient global amnesia is reported to be caused by cerebral venous congestion.[] . • In less severe cases, consciousness if lost may be regained in minutes to hrs • Residual drowsiness, confusion and amnesia accompanied by severe headache may persist for[]

  • Subdural Hematoma

    Trauma Cause(s) In most cases, an injury to the top of the skull Symptoms Loss of consciousness, irritability, seizure, pain, numbness, headache, dizziness, disorientation, amnesia[] […] injury Loss of consciousness or fluctuating levels of consciousness Irritability Seizures Pain Numbness Headache (either constant or fluctuating) Dizziness Disorientation Amnesia[] This period will approximate the duration of posttraumatic amnesia.[]

  • Neurosyphilis

    A diagnosis of neurosyphilis should be considered in patients with serologic evidence of syphilis and one or more of the following cerebrospinal fluid abnormalities; mononuclear[] Diagnosis of neurosyphilis should be suspected in the presence of a global cognitive impairment consisting in disorientation, amnesia and severe impairment of speech and judgement[] Cerebrospinal fluid abnormalities in patients with syphilis: association with clinical and laboratory features.[]

  • Susac Syndrome

    Cerebrospinal fluid was abnormal in 5 patients showing pleocytosis (mean, 24.6; range, 6-85 cells/mL) and elevated protein level (mean, 210; range, 113-365 mg/dL).[] […] partial status epilepticus ) Headache Migraine ( Familial hemiplegic ) - Cluster - Vascular - Tension Vascular Transient ischemic attack ( Amaurosis fugax, Transient global amnesia[] The EEG showed frontal intermittent rhythmic delta activity.[]

  • Cerebral Hemorrhage

    Cerebrospinal fluid (CSF) studies disclosed mononuclear pleocytosis with elevated protein levels.[] This can cause memory problems particularly antegrade amnesia.[] Results of a polymerase chain reaction assay of the cerebrospinal fluid were positive for HSV-1. His course was complicated by 2 episodes of cerebral hemorrhage.[]

  • Brain Neoplasm

    For example, blood and cerebrospinal fluid may also be tested to check for substances secreted by tumors (called tumor markers) and for gene abnormalities that are characteristic[] I became the man who remembered events I had never experienced, due to my amnesia.[] 3 months; new parictal lesion. deficits and with mass effect abnormalities; Dx: MS BAEP Brain stem auditory evoked potential, CC corpus callosum, CSF cerebrospinal fluid,[]

  • Cerebral Neoplasm

    This is a sac of cerebrospinal fluid (CSF), which has been "trapped" outside or inside the brain. It might also be called a "leptomeningeal cyst."[] Recent evidence suggests that specific chromosomal abnormalities may predict the response to chemotherapy.[]

  • Limbic Encephalitis

    Cerebrospinal fluid test results were abnormal in 18 (78%) of 23 patients tested.[] We report a case of limbic encephalitis in a 56-year-old man, revealed by anterograde amnesia.[] Abnormalities in cerebrospinal fluid and electroencephalogram were commonly observed (92% for both). Tumors were not identified in any cases.[]

  • Metabolic Encephalopathy

    The cerebrospinal fluid can also be analyzed for abnormal proteins, chemicals, and cells.[] Ophthalmoparesis, gait ataxia, and a confused state Amnesia B1 alcoholism Give thiamine BEFORE glucose for proper glucose metabolism Labs transketolase decrease What areas[] […] patterns, e.g., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions.
